science say the reef has lost half of its coral cover over the past 27 years. there are multiple causes, including a destructive kind of starfish shown here. we look at what's behind it and what's at stake-- in australia and around the world-- with nancy knowlton, a coral reef biologist and a chair of marine science at the smithsonian national museum of natural history here in washington. welcome. >> thanks. how has all of this coral died off? do we know what's causing it? is it all that... >> it's not all the star fish. the star fish is about 42%. typhoons, big strong storms another 48% and then coral bleaching is the remaining 10% which is caused whenever the water gets too hot. >> ifill: so this is human causedded? >> yes. most of it is human caused. i mean a coral reef naturally goes through cycles of up and down. but it shouldn't be declining by half over course of 27 years. >> ifill: i feel like we have talked before about the declining coral cover. but not... but i'm wondering whether it's now picking up speed or whether this is just a natural deterioration that we should just be

, so now i want to hire another 100,000 new math and science teachers, and create two million more slots in our community colleges so that people can get trained for the jobs that are out there right now. and i want to make sure that we keep tuition low for our young people. when it comes to our tax code, governor romney and i both agree that our corporate tax rate is too high. so i want to lower it, particularly for manufacturing, taking it down to 25%. but i also want to close those loopholes that are giving incentives for companies that are shipping jobs overseas. i want to provide tax breaks for companies that are investing here in the united states. on energy, governor romney and i both agree that we've got to boost american energy production, and oil and natural gas production are higher than they've been in years. but i also believe that we've got to look at the energy sources of the future, like wind and solar and biofuels, and make those ininvestments. so all of this is possible. now, in order for us to do it, we do have to close our deficit, and one of the things i'm sure

want to take it out of the framework of being a science fair project and give it to the opportunity to take on the goliath problem of the 21st century, bad water, we call the project slingshot because slingshot was the little piece of technology that was given to david and as the kid i remember the story of david and goliath and the moral to me was you use technology properly, slingshot and you will take out goliath. >> rose: so what do we have here? i want to show it in just a moment. >> so in this little accurate scale model of a shipping container which could be put into a village, is -- >> rose: shipping container. there is an actual model of a standard shipping container, this is eight feet by ten feet by 20 feet, here is the actual scale model next to a person of the slingshot. >> rose: right. >> it makes 1,000-liters of water a day and even if you closeup at night and hopefully the women that will run this downtown, it will sit inside here all night filling up thousand liter reservoirs that are accessible outside so all day and all night people can get clean water, be but bas

voters turn out where. dave robertson, a political science professor at the university of missouri st. louis, says the topsy-turvy election has cut both ways. >> one of the things akin has been able to do is electrify some of the conservative base. but there's a counter movement to that. and that is he's also helped electrify some of the female voters in the state, some of the moderate voters in the state, some of the key voters in the suburbs of this state that are going to determine the outcome of this election. and that's a real disadvantage for him. >> ifill: akin is counting on conservatives, home schooling parents, and evangelicals to rally around his cause. >> we don't tell you who to vote for, but i'm going to tell you how to vote. >> ifill: reverend stoney shaw, pastor of ferguson first baptist church, has known akin for 25 years. >> some of my family, my children were, "dad, how can you support him? everybody is turning against him." i said, "you know, there was another guy everybody turned against-- jesus christ-- but he prevailed. and i believe todd will prevail. he's a go

results in just two days. the research was published in the journal, "science translational medicine." the paper reported the tests of just six newborns in neonatal units, but the implications could be widespread. roughly 20% of infant deaths in the u.s. are caused by inherited genetic conditions, according to the study. doctor stephen kingsmore led the research team at children's mercy hospitals in kansas city. he's the director for the center for pediatric genomic medicine there. dr. kingsmore, welcome, and thank you for being with us. first of all,-- >> thank you very much. >> warner: how big a breakthrough is this? >> this is a big breakthrough. we've been working toward this goal for a coup of years now. there has been a big gap between the knowledge that we have of genetic diseases, about 35% of them, and the ability for doctors to identify which of these was a problem in any given child with an illness. >> warner: and up until now, how much have you been able to diagnose the d.n.a. abnormalities? how quickly? i mean, i said it can take weeks and weeks, but what's the process that's
